Why Is Your 2023 Tahoe Engine Locked Up?

In April 2025, GM issued a stop-sale and broad recall citing a safety defect with their engines.

According to GM’s recall and investigation report, your 2023 Chevrolet Tahoe engine may have problems related to rod-bearing contamination, improper crankshaft machining, and debris in oil galleries. All of these issues can lead to catastrophic failures, such as:

  • Bearing Failure: Sediment in connecting rods or oil passages can destroy rod bearings, causing the engine to seize
  • Rod/Crankshaft Defects: Factory errors in crankshaft specs or surface finish can compromise engine integrity
  • Fuel Pump Module Problems: Less commonly, fuel pump issues could trigger engine shutdown
  • Contributing Factors: Oil pressure warnings, gasket leaks, or carbon-deposit-induced lubrication failures can compound overall risk

Unfortunately, this problem with Chevrolet Tahoe engines isn’t isolated. It affects all GM trucks and SUVs built between 2019 and 2024 with the 6.2L V8 L87 engine, including the Yukon, Suburban, and Cadillac Escalade. If your 2021 GMC Yukon engine seized recently, you’re also among those affected.

Common Signs Your 2023 Tahoe’s Engine Has Locked Up

Even if your engine hasn’t fully seized, you might still notice warning signs. Early detection can be life-saving, helping you prevent a complete breakdown and a costly engine replacement.

If you’re experiencing any of these symptoms, take your Tahoe to a certified mechanic or dealership immediately.

Sudden Loss of Power While Driving

Your Tahoe may stall with no warning, often without triggering a check engine light. Drivers report vehicles suddenly cutting out while merging onto highways or at intersections, creating dangerous situations.

This abrupt loss of power could indicate an internal failure caused by oil starvation or bearing wear that’s already progressed too far.

Clicking or Clunking Noise When Starting the Engine

Loud clicking, clunking, or knocking sounds when starting often signal broken internal components like failed lifters or damaged bearings. These noises may worsen over time or after failed start attempts.

Complete Failure to Crank or Start

After stalling, the engine may refuse to restart, indicating severe internal damage. In some cases, the vehicle may attempt to crank but fail to turn over, or remain completely silent when you press the start button.

This could be the result of a catastrophic engine lockup caused by insufficient oil circulation, rod bearing failure, or crankshaft defects.

Burning Oil Smell or Smoke From Engine Area

Light grey or blue smoke from the hood, often with strong, acrid odors, indicates oil burning internally due to component damage or gasket leaks.

Don’t ignore these warning signs. If your 2023 Tahoe is experiencing engine problems that GM cannot permanently repair, you may be entitled to a replacement vehicle or full refund under Lemon Law protections. Time is of the essence as vehicle age and mileage can affect your claim.

What to Do if You’re Concerned About Your Tahoe Engine

Even if your truck isn’t having major problems yet, you still have options. These engine issues are hard to spot before they happen, so here’s what you should do to protect yourself.

Contact Chevrolet

Get in touch with Chevrolet right away to get this on record. This creates a paper trail that could help you later. Dealers can’t sell these trucks right now until they’re inspected.

Seek Professional Diagnosis

Get your Tahoe inspected under the recall as soon as possible. The dealer will run diagnostics and check the engine internals to see if you need repairs or a whole new engine.

Document Everything

Keep copies of all service records, communications, and diagnostic reports. These are vital if a lemon law or warranty claim becomes necessary.

Learn About Your State’s Lemon Law

Lemon laws protect you when manufacturers can’t fix serious defects after multiple repair attempts. Each state has different rules, but most require the manufacturer to give you a refund, replacement, or cash settlement if they can’t permanently repair your vehicle.

For your Tahoe, this typically means if Chevrolet can’t fix your engine problems after 3-4 attempts, or if your truck is out of service for 30+ days for repairs, you may qualify for protection. The law usually covers vehicles still under warranty or within the first few years of ownership.

Time matters with lemon law cases. Most states have deadlines, and waiting too long can hurt your claim. If you’re dealing with repeated engine problems, it’s worth understanding what your state requires and what compensation you might be entitled to.

Consider Legal Action

If Chevrolet won’t cover your repairs or keeps denying warranty claims, you don’t have to accept that as the final answer. Manufacturers often resist expensive repairs like engine replacements, even when they know there’s a defect.

You have the right to pursue legal action if Chevrolet isn’t honoring their obligations. This could mean filing a lemon law claim to get the compensation you deserve. An experienced attorney can evaluate whether your situation qualifies and handle negotiations with Chevrolet’s legal team.

FAQ

Yes. In April 2025, GM recalled 2021–2024 6.2L V8 SUVs—including the Tahoe—due to engine defects. Affected owners are being contacted via mail for free inspection and repairs.

This refers to sudden engine seizure—typically due to manufacturing defects in GM’s 6.2 L V8 (L87) engine. The core issue involves internal connecting‑rod bearing failures and crankshaft defects—often with no warning, such as a check-engine light—leading to abrupt loss of propulsion or engine shutdown.

A class action has been filed alleging GM knew about 6.2L engine defects but continued selling affected vehicles.

Under the recall, GM covers all costs, including engine replacement, towing, inspections, and rental cars.

No widespread transmission issues. Some owners report minor problems like steering column errors, but these are unrelated to the 6.2L engine defect.
